XVILLIAM H. HOOPER, OF TORRINGTON, CONNECTICUT.

WINDOW LOCK AND REGULATOR.

SPECIFICATION formingpart of Letters Patent N0. 688,089, dated December 3, 1 901.

Application filed August 5, 19(l1- Serial No. 70,870. (No model.)

To all whom it may concern:

Be it known thatI, WILLIAM H. HooPER, of Torrington, in the county of Litchfield and State of Connecticut, have invented a new and useful Improvement in \Vindow Locks and Regulators; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a front or plan View of a window lock and regulator constructed in accordance with my invention; Fig. 2, a sectional View on the line a Z) of Fig. 1; Fig. 3, a side view of the knob detached.

This invention relates to an improvement in window locks and regulators, and particularly to that class of devices which are arranged to lock the sashes together, so that either the upper sash may be lowered or the lower sash raised, the object being to produce a device simple in character which may be readily applied to all window-sashes; and it consists of a plate adapted to be secured to the side rail of a sash and provided with a slot in which a knob or button may travel and with an offset at one end into which the button may be turned to permit the unrestricted movement of the sashes, and in certain details of construction, as will be hereinafter described.

As herein shown, the device consists of a plate A,adapted to be secured to the face of the side rail B of the upper sash, and at the lower end it is formed with a projection C, preferably bowed, as shown. In this projection is a horizontal slot D, terminating at the outer end with a notch E. From the inner end of the slot D, which extends into the plate, a slot F extends upward through the plate and terminates near the upper end in a notch a, Preferably this slot will be a zigzag slot, as shown, so as to form shoulders G, more or less in number. Within the slot is the shank I of the knob J, the shank being provided with a head K, which rests in a groove L, which follows the lines of the slots in the plate. In connection with a device of this character a strike-plate M maybe secured to the upper rail of the lower sash in line with the plate A. When not required for use, the knob J is turned through the slot D and so that the shank I rests in the notch E, in which position the knob is out of line with the rails of the lower sash, which may be freely moved in the usual manner. When it is desired to limit the upward movement of the lower sash or the downward movement of the upper sash, the knob is passed from the slot D'into the slot F, through which it is free to travel by the movement of the sashes, and the movement of the sashes will be arrested by the upper end of 'slot 1 or by either of the breaks therein. If desired, the knob may be passed to the upper end of the plate, so as to restin the notch a. It will thus be seen that the movement of the sashes may be positively limited and the extent of their opening adjusted as desired, and when not required the device is thrown out of operation.

By forming the groove for the reception of the head of the shank of the knob the device may be placed upon the face of the windowframe, and therefore applied without cutting or mutilating the sashes.

As herein shown, the device is arranged to be applied to the lefthand side of the sash; but it is apparent that the projection at the bottom of the plate might extend from the opposite side, so as to adapt the device for attachment to the right-hand side of the sash.

I am aware that window and door fasteners comprising a slotted plate and with a locking member adapted to slide therein are old; and I do not therefore wish to be understood as claiming, broadly, such as my invention; but,

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. A window lock and regulator comprising a plate formed with a side extension at one end, a longitudinal slot in said plate connecting with a slot in said extension, and a knob arranged to slide in said slots substantially as described.

2. A window lock and regulator, comprising a plate having a bowed extension, a slot in the said extension, and a zigzag slot in the said plate with which the slot in the extension connects, and a knob arranged to slide in said slots, substantially as described.

3. A window lock and regulator, comprising a plate having a bowed extension at one end, and a slot extending through said plate and into said extension, a groove in the under side of the plate following said slot, a knob, the shank of which extends through said slot, and a head on the end of said shank within said groove, substantially as described.

WILLIAM H. HOOPER.
